A. O. KETGHUM, OF NEW YORK, N. Y., ASSIGNOR TO WM. P. PETTINGILL AND S.T. MGDO UGALL.

IMPROVEMENT IN COAL-OIL LAMPS.

Specification forming part of Letters Patent No. 40,080, dated September22, 1863.

To all whom it may concern:

Be it known that I, A. O. KETGHUM, of the city, county, and State of NewYork, have invented a new and useful Improvement in the Construction ofKerosene or Goal-Oil Burners and I do hereby declare that the followingis a full and exact description of the said lnvention.

The nature of my invention consists in providing the wick-tube with across-bar running at right angles with the same, and attached to eitherthat or the base, or both, for the purpose of causing the air to enterthe jacket or deflector on either side, independent of the other, sothat when the lamp is carried through the air the cross-bar or partitionwill act as a deflector and cause the air to rush upward, therebystrengthening the flame, whereas, were it not there, there would be acurrent directly across the base, and draw the flame down and put itout. It also forms an excellent restingplace for the jacket ordeflector. The bearing of the deflector being so small upon thepartition that it neither gives nor receives much heat, it also leaves afree admission of air, as it touches nothing but the small point abovementioned.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction.

Figure 1 is a vertical section. Fig. 2 is a side view of the same.

Gorrespondin g letters indicate the same parts.

Ais the base thatscrews in the socket of the lamp. B is the wick-tube. Ois the roller for adjusting the wick. D is the jacket or deflector. E isthe crossbar-or partition attached to the tube B, D having a slot cut ineach side of its base, as shown in Fig. 2, so as to slip down each sideof partition E, with a shoulder at each end of partition E to hold it inits place firmly both ways, which is shown in Fig. 1.

Having thus fully described the nature of my invention, what I claim,and desire to obtain by Letters Patent, is

1. The application of the partition or cross-v bar E to the tube B andbaseA.

2. The peculiar mode of attaching the jacket D, as shown in Fig. 1.

3. The combination of the jacket 1) with the partition E, and attachedto the tube and base, B and A, substantially as described, therebymaking a simple and economical burner.
